To all 'whomt may calimera/:J` Be it known that I, JEREMIAH J. Frrz- PATRICK-a citizen of the United States, re-

siding at Tulsa, in the county of Tulsa 'and State of Oklahoma, have invented certain new 'and useful Improvements in Intakes for.:

Oil-l-Vell Pumps, of which lthe following is al specification.

This invention relates to intakes for oil wellpumps.

An object of the invention is the provision of an intake that will permit water and oil to be pum from a well without pumping an appreciable quantity of sand.

A further-object iste provide an intake, that is a sand and gas eliminator, arranged entirely below the working barrel, *wherebyV the sand and gas will be kept away from the valves and valve seatsin t e working A further object is to provide an intake that permits-the law of gravity to function in the separation of sand and gas from oil and water and having no valves' therein, the

I 2l! life of the intake is prolonged.

Xln the accompanying drawings, I l,have shown one embodiment of the invention. .In this showing: Y

l Figure 1 is a front elevation of the device in position within a well.

' Figure 2 is a vertical view.

Figure 3 is a horizontal view en line 3-3 of Figure 2.

. Figure 4 is a horizontal seetional 'view on line 4 4 of Figure 2, and,

Figure 5 is-a similar view on line 5-5 of Figure 2.

Referring to the drawings, the reference numeral 1 designates the'. lower end of' a I Working barrel, arranged within a well. This working barrel is provided with the vusual standing valve 2 at the bottom, and

traveling valve 3 above the standing valve. The apparatus forming the subject matter of the present invention consists of an enlarged bowl or easing 4 having reduced up-v per end 5. This upper end is threaded and' 1s adapted to receive'the collar of the lower section of the working barrel. The-lower end. of the bowl is provided with athreaded portion ou theinside 6, ladapted to receive pipe 11. The upper portion of 7, biz- A in the lower portion of the bowl,-is' provied with a plurality of concave recesses 56 8, extending downwardly :from near the botthe bowl 4 as shown in Figure 2.

Y tom 'of theebowl and communicating with the interior of pipe 11. The recesses are pro- -vided with '-inner walls 9. The bottom 9 'of the bowl 4 is threaded on the inside 10 to receive intake-pipe 12. As shown in Fi 6&1 the intake'pipe 12 extends upward y .within the bowl 4. The lower end of pipe V.11 is swaged 'or hushed down, and 'threaded on the inside to receive lug 13 or to attach anchor pipe or to be eft open according 6B to the status of the oil well.

. The pipe 11 is perforated at 14, above the bottom 13 and below4 the bottom of intake 12 to allow the water to be pumped' `ovv the recesses 8 or to be closed aecord- 70 in to 'tlieoilv well.V

he working barrel is arranged in a well 15 with the intake. disposed beneath't. It willb'e apparent that-'the valves and valve f seats are arranged above the. intake and the 76 sand and gas separatedfrom the water and oil by lthe downward motion of the fluid from reeesses 8 to the bottom of intake pipe 12 and inthebowl 4xbefo'reit reaches any valies'and valve seats, thus minimizing wear so on these parts andthe working barrel roper, dueto the'cutti effect of artic es of sand and unseating t e ball in t e-standing valve by gas pressure.

When' the pumping operation is first 86 lstarted if the oil well is` making some water,

the water passes through 4tbe recesses 8 until the' water is pumped to the level'thereof, then it enters vthe perforation 14 until itis pumped below the bottomof intake pipe 12 ,90

andas the oil is always on top of the water,V then it'will pump oil, as it will pump only the fluid that the bottom of the intake pipe 12 is submerged in. vAs the oil passes through the recesses' 8 it is given the downward moi tion until it reaches the bottom of the intake 12 and any sand that is heavier than oil or water will keep on going downward by the .law of gravity. The fluid is then taken up in the'bowl l#through the intake pipe 12 and 100 there being a volume of Huid lying dormant to enter the working barrel, any sand that may have reached the bowl 4 would settle around the outside of the intakepi: 12 in is no rush of oil at any time within the intake, all .the openings being many times larger than the openingin the valve seat of the standing valve 2, it allows plenty of time for the law of gravity to function and elimi- Slo there A notes the breathing eectommon to devices 110W 1R USS. Y

The fiood hole 16 in the top of the bowl'Yl l is for the pur e of the Working barrelre! ceivinif air 'w ienever the duid is pumped down to that level, thereby keeping what" lever portion of the oil sand coveredwith oil as'is desired.

The oil never' enters the perforation 14. on account-of thecushionof water lying in the bottom of the well and incasing 1l Just below the intake pipe 12, 'but always enters at Y the recesses 8. ,'With proper installation of sand covered lwith oil in pleceofwater,

the cross-sectional aree of said working barthis intakethe water can be puinmd. from the bottom of thewell first and keep the oil which would here Aa tendency t'o increase oil produc-tion and raise the gravity of the oil. In a vast majority of oil wells this plug 13 in the bottom of casing 11 would be left out which would allow thesand to Siphon down -the inside of casing 1l and pipe 12 and ont through the opening 13 to-the'bottom-of the well.

It is to be understood'that the form-df the`l invention herewith shown and described Ais to betaken as a preferred example pi thesame and that various changes in the shape, size, construction anderrangeme'nts of parts may be resorted to Without,departingfrom the spiritof the invention or the scope .of the subjoined claims.
